Overview
36VHigh-performance, High-reliability Withstand Voltage Stepping Motor Driver BD63720AEFV ●General Description BD63720AEFV is a bipolar low-consumption driver that driven by PWM current.
Rated power supply voltage of the device is 36 V, and rated output current is 2.
0 A.
CLK-IN driving mode is adopted for input interface, and excitation mode is corresponding to FULL STEP mode, HALF STEP mode (2 types) and QUARTER STEP mode via a built-in DAC.
In terms of current decay, the FAST DECAY/SLOW DECAY ratio may be set without any limitation, and all available modes may be controlled in the most appropriate way.
In addition, the power supply may be driven by one single system, which simplifies the design.
● Features ■ Rated output current（DC）2.
0A ■ Low ON resistance DMOS output ■ CLK-IN drive mode ■ PWM constant current (other oscillation) ■ Built-in spike noise cancel function (external noise filter is unnecessary) ■ Full-, half (two kinds)-, quarter-step functionality ■ Freely timing excitation mode switch ■ Current decay mode switch （linearly variable FAST/SLOW DECAY ratio） ■ Normal rotation & reverse rotation switching function ■ Power save function ■ Built-in logic input pull-down resistor ■ Power-on reset function ■ Thermal shutdown circuit (TSD) ■ Over-current protection circuit（OCP） ■ Under voltage lock out circuit (UVLO) ■ Over voltage lock out circuit (OVLO) ■ Ghost Supply Prevention (protects against malfunction when power supply is disconnected) ■ Adjacent pins short protection ■ Microminiature, ultra-thin and high heat-radiation (exposed metal type) package ● Application ■ PPC, multi-function printer, laser beam printer, and ink-jet printer ■ Monitoring camera and WEB camera ■ Sewing machine ■ Photo printer, FAX, scanner and mini printer ■ Toy and robot ● Major Characteristics ■ Range of power supply voltage 19～28 [V] ■ Rated output current (continuous) 2.
0 [A] ■ Rated output current (peak value) 2.
